They may not have heard anything new, but lots of Obama supporters I've talked with today were happy just to hear his familiar stump speech live. Like Tiffany Keenan, 32, of Portland, who said Obama's speech was "very powerful."

"Portland is an empowering place to live and to have so many people out here is just amazing," she said.

And then there was Terri Ducan, 59, of Portland, who summed up Obama's rousing talk this way: "It was Obama."

She said she'd heard a lot of what he'd said before but it didn't matter. He repeated the things that mean most to her this election, including change.
